The hexadecimal error 0xe00086cc in Backup Exec typically indicates a communication or permission failure between the Backup Exec server and a target resource, such as a remote agent or a storage location like a Backup-to-Disk (B2D) folder. This error often manifests during backup job initialization or when attempting to write data to a backup destination, generally accompanied by messages like "Unable to create new backup folder. Access denied" or "A communications failure has occurred" .

If you have recently upgraded Backup Exec but not updated all remote agents, version mismatches may cause connection failures. This is especially common when upgrading from Backup Exec 2012 to newer versions. Uninstall the existing Backup Exec Agent for Windows or Remote Agent from Add/Remove Programs on the target system, then redeploy the agent from the Backup Exec console.
